Adriaan Tijsseling, developer of the Mac OS X version of the ecto blogging client, has been teasing us with sneak peeks and development details for some time now, but he's just posted another more revealing screenshot of ecto3, along with more details and a basic roadmap. Adriaan has touted ecto3 as a complete rewrite from v2, ushering in a new plug-in architecture that should make the app far more extensible.
Also on the notable changes list is the replacement of the rich text editor by Editable WebKit, a new, more WYSIWYG feature of the engine that is used to power Safari, many other browsers on Mac OS X and even HTML rendering in Apple Mail.
While Adriaan doesn't have any kind of ETA for a shipping version or even a beta just yet, it does sound like development is wrapping up well. Since support for different blogging platforms has moved to the plug-in format as well, he still has to build support for the latest Blogger (yes, it'll be in ecto3) and WordPress. As a final note, it's always nice to hear a developer using their own product, as Adriaan is using ecto3 "heavily" to try and catch as many bugs and problems as he can before unleashing it in one form or another on the masses.
